Answer:
(-5, 4.5)
Explanation:
The midpoint formula is:
(x1 + x2) / 2, (y1 + y2) / 2
All you're doing is taking the average of the x coordinates and the average of the y coordinates.
You have that x1 = -3, x2 = -7, y1= -2, y2 = 11 so you can plug that in:
(-3 + -7) / 2, (-2 + 11) / 2
(-10) / 2, (9) / 2
(-5, 4.5) is the coordinate
